How can I link multiple CRM accounts to one online record store?

[LoveAnarchy]

I am running a store which is for a Record Label. Each artist on the label has their own collection on the store. Right now I am using Drip CRM for my email marketing, which syncs nicely to the store and pulls in necessary data such as purchase history.

The problem is I want to be able to create individual CRM accounts for each artist, that they can then access and send emails to their list. But only one Drip account can be synced to my Shopify store.

I do not wish to add each individual artist as a user to my single Drip account, as there'd be a high risk of them sending emails to the wrong people, or generally messing things up.

Is there any solution for this problem? I am open to working with any CRM that will allow me to create separate users/accounts for each artist to only have access to their list, whilst having them all still connected to the Labels Shopify Store.

Please let me know if you have any ideas!
